Hey Nicolas,
I tried a simple rewrite of Peter's text.  Does this work for you?

While Netoptics makes optical regen taps (up to 16 monitor ports  
again) if you only need a two port unit, two %80/%20 optical taps can  
do the trick. The two %80 taps connect in series along the monitored  
link introducing a %36 power attenuation (80% and then 80% again).   
This additional "hit" is significant, so do watch the power budget on  
all the links!   The two monitor ports will end up with 20% and 16% of  
the power.   A real regen tap is a better (but more expensive) bet as  
it will regenerate the signals and give you full strenght out the  
monitor ports.
